Given that Egghead has become a battleground for many powerful Marines, pirates, and of course, even World Government officials, there have been many strong Haki users that Oda has showcased in this arc. Of course, among all of them, only a few can be considered to be the very best.

10Rob Lucci

Haki Types: Armament, Observation

Rob Lucci is a member of the CP0 and certainly a very powerful individual. As a masked member of the group, Rob Lucci ranks among the strongest in the CP0 organization. In Egghead, he showcased new powers, such as an awakened leopard Zoan Devil Fruit, and of course, improved Haki.

He went up against Zoro in the Egghead Island arc, and certainly did well. However, his Haki was not strong enough to withstand Zoro’s powerful blows and eventually, he was cut down by the Straw Hat Pirate.

9Sanji

The cook of the Straw Hat Pirates, Sanji is an excellent user of Haki as well. As was confirmed in Wano, Sanjay has finally refined his Armament Haki, and he is a master of Observation Haki. In fact, he might just be one of the very best users of Observation Haki on egghead.

Sanji saved many characters using his powerful Observation Haki in Egghead, and using his Armament, took part in many battles where he had to bring out his very best.

The Admiral of the Marines, Kizaru is a very powerful Haki user, as is expected of him. He can utilize both Observation and Armament Haki at a high level, and he utilized it extensively during his many fights, such as when he clashed against Santomaru, and later on, Luffy.

7Roronoa Zoro

The swordsman of the Straw Hat Pirates, Zoro primarily relies on Haki in battle. Zoro makes use of all three Haki types, and while his specialty is Armament Haki, his strongest type of Haki is Conqueror’s.

St Marcus Mars is also one of the Five Elders, and the user of the Itsumade Yokai transformation. When he was summoned on Egghead, he immediately went for the Frontier Dome. To pierce the Dome, he made use of his powerful Conqueror’s Haki and broke through it.

Jinbe witnessed his Haki and was utterly shocked at how powerful it was. According to Jinbe, his Haki is monstrous and that is why he, along with Zoro, decided to simply run from him.

He possesses great control over Armament Haki, and it goes without saying that he possesses Conqueror’s Haki as well. While fans have not seen his proficiency with this skill, he’s sure to be a master of it.

2Saint Topman Warcury

Haki Type: Armament, Observation, Conqueror’s

St Topman Warcury is one Elder who has already showcased incredible usage of Conqueror’s Haki in the series already. When he was fighting against Luffy, he used his Conqueror’s Haki roar and completely blew away some parts of the straw hat pirate.

Meanwhile, his Haki was so strong that even two Giants, such as Dorry and Brogy, could not withstand the pressure properly. Individuals on faraway ships started losing consciousness, and that just goes to show how strong Warcury’s Haki is.

Of course, the individual with the strongest Haki on the Egghead is none other than Luffy. Luffy possessed tremendous Haki that he has advanced across all three types.

His strongest Haki type is certainly Conqueror’s Haki, and he has developed the skill amazingly ever since the conclusion of Wano. He utilized this power in his battle against Admiral Kizaru and completely took him down in one blow.
